Hello,
I found your library and wanted to test it for basic purposes, but I am unable to complete.
My (first) goal would be to convert 16bits values to 4x8bits (scaling 16Gray images to 32bits Bgra images).
The shader looks like this :
[AutoConstructor]
public partial struct Scaling : IComputeShader
{
// Other captured resources or values here...
public ReadWriteBuffer<int> Source;
public readonly int min;
public readonly double scale;
public void Execute()
{
int rgb = (int)(scale * (Source[ThreadIds.X] - min) + 0.5);
Source[ThreadIds.X] = (rgb << 24) | (rgb << 16) | (rgb << 8) | 255;
}
}
and the function that calls it :
static public void GPUScale16Grayto32Bpp(ref Bitmap src, ref Bitmap dest, int pixel_type)
{
ushort max = (ushort)(Math.Pow(2, pixel_type) - 1);
ushort min = 0x0000;
double scale = 255.0 / (double)(max - min);
BitmapData src_data = src.LockBits(
new Rectangle(0, 0, src.Width, src.Height),
ImageLockMode.ReadOnly, src.PixelFormat);
Int16[] src_array = new Int16[src.Width * src.Height];
int[] dst_array = new int[src.Width * src.Height];
IntPtr ptrFirstPixel = src_data.Scan0;
Marshal.Copy(ptrFirstPixel, src_array, 0, src_array.Length);
src.UnlockBits(src_data);
ReadWriteBuffer<int> buffer_src = GraphicsDevice.GetDefault().AllocateReadWriteBuffer(Array.ConvertAll<Int16,int>(src_array, x => (int)x));
GraphicsDevice.GetDefault().For(buffer_src.Length, new GpuFonctions.Scaling(buffer_src, min, scale));
BitmapData dest_data = dest.LockBits(
new Rectangle(0, 0, dest.Width, dest.Height),
ImageLockMode.WriteOnly, dest.PixelFormat);
IntPtr ptrFirstPixel_dest = dest_data.Scan0;
buffer_src.CopyTo(dst_array, 0);
Marshal.Copy(dst_array, 0, ptrFirstPixel_dest, dst_array.Length);
dest.UnlockBits(dest_data);
}
I get an exception message at Runtime when reaching this line : PipelineData pipelineData = PipelineDataLoader<T>.GetPipelineData(this.device, threadsX, threadsY, threadsZ, ref shader);
ComputeSharp.Exceptions.DxcCompilationException
HResult=0x80131500
Message=The DXC compiler encountered one or more errors while trying to compile the shader:
Unknown argument: '-Werror'.
Make sure to only be using supported features by checking the README file in the ComputeSharp repository: https://github.com/Sergio0694/ComputeSharp.
If you're sure that your C# shader code is valid, please open an issue an include a working repro and this error message.

I tried different things, but nothing worked so far, and I get the same exception.
I am on VS2022, I updated my projects to sdk style projects, I target .NetFramework 4.8 (due to other old library).
I used Nuget to get the packages ComputeSharp, ComputeSharp.Core, ComputeSharp.Dynamic and ComputeSharp.Pix in version 2.1
The graphic card is a GTX 1050, which seems to be well found.
I am wondering if I may have mixed functions not compatible between version 2.1 and examples of version 3 ?
Or do I miss something obvious ?
Thank you for the feedback.
